From: Sam on 22 Mar 2010 05:43 Hi all, I need to write a code for adding two vectors of different length, e.g. x=[1 9 8] and y=[2 0 4 9], treating the row vectors as integers. Any help will be appreciated.

Any help will be appreciated. But what do you want or expect as result??? What does "add" mean, if the vectors have different sizes?! Kind regards, Jan

If you are expecting element-wise addition, then is the implication that the shorter vector is to be extended with zeros before doing the additions?

I need to add zeros at the front of the smaller number so that I can add the two up. For example x would become [0 1 9 8]. Also when they add up I need the number to extend as they must all be single digits. [9] + [8] must become [1 7] not [17]. Sam |
